Relining Brake Bands

Tue Mar 05, 2013 9:35 pm

I got the Demo Cub rear end torn down and found literally NO brake lining left on the brake bands. So I went looking for replacement bands and my bands are the ones with no toggle, the rod is welded to the strap steel. So I found out how much a new replacement cost and I about choked and then asked myself where can I get just a new lining??

I did a search here for brake bands and found a HOW TO, by Raymond Durban on how to reline brake bands. Very helpfull info.

Well I went to McMaster's web site, found the needed supplies, ordered extra incase I screwed up, and so I ordered it Sunday night and it showed up today.

I followed the steps in the video and was able to get one started tonight. I ran into a problem when it came to setting the rivets, I need to make a rivet punch jig?

So I found an old C-Clamp and got the flat end off of it and tried to compress it down. It worked ok but I got to a point where the rivet started to spin. So I am going to school eary in the morning to see if I can't machine a better head on the C-Clamp screw so it spreads the rivet out better.

Or better yet, I may have a rivet setter around and I don't even know it.

Just thought I would throw my experience out. With just about 30 mins of my time I could of had one band down and save a around $100 in the process by the time I'm done with the two.

Use the punches depicted later in the video. Flat punch to fit the flat head of the rivet held in a vise - facing up. Set band and lining in place, with loose rivet installed. Cone shaped punch to spread the rivet.

Set rivets in place - punch set loose. Once satisfied start in center of band and tighten up rivets.

As Eugene said, start with a center punch and then finish with a flat punch. A rivet set will roll the edges over smoothly and it will look nicer, but only if you have the right size rivet set.

I simply used a piece of 3/16 rod that i rounded off on the grinder and clamped in the vice point up. I then used a piece of 3/8 rod to "set" the rivet with a hammer. Then i finished the rivet off on the anvil. Worked great on the lining side, didnt look that great on the band side, but my brakes now work great and not one person that has looked at my cub has said "gee those rivet collars sure are ugly".

I got my bands done. It was not that bad at all once I made or found tools for the job.

I took several pics and will go through what I did below.

This is what I started with

Next I drilled The rivets out with a 3/16" drill bit

Next I cut a piece of band to 12" exact length, measured from an old one.

Next I fit the band inside the steel band and clamped it in place and then marked my holes.

Being a woodworking gu-ru, I had a step drill that use for my pocket drill system. The step drill, drills a pilot hole and then counterbores the hole to 3/8". This worked perfect or you could use a 3/8" forstner bit which I had to.

Once drilled, they look like this.

Next I fit the rivets and I made a press using a C-Clamp to start the flare of the rivets.

After tool.

I then used a roll pin punch to hammer them down farther.

The roll pin punch didn't get them all the way snug, so I used a small Ball-Peen hammer or a flat round punch to finish the job of working them down snug.

Has anyone tried doing this job w/bonding cement?? At one time had a website that had guaranteed cement for bonding brake shoes?? Dusty B

Dusty,I got a brake lining from CIH years ago that was supposedly glued on. All I can say it did not not hold up at all, it spun in a few days. I was thinking of glue and rivets but since it was just riveted in the first place I used rivets. I even got some epoxy out before I changed my mind.

Nice job Jason. Those won't need to be redone for another 40-50 years.

Nice. Bob helped me out with a set of toggle ones at Cecil's fest. They surely have gotten expensive!

I don't like the idea of glue, but I am sure there is some good stuff that would work.

Sometimes you just need to bite the bullet and do a brake job

That one ugly brake. Glad mine was caught just in time. I am now doing all seals in the rear end and final drives, It has turned into a nightmare on the axels, I missed with the hammer and smashed my fingure and the threads up at the same time and now I need a new axel as the nut threads got stripped out when I tried putting it back on. Good thing I got a parts tractor around.

I had it up on the bench and it slid off my support, so tonight I said there was no price on safety and spent the money and bought a 20 ton press, shop crane, a floor jack, and several other pullers and stuff with all my coupons at Harbor Frieght, their tent sale is going on now and some things are cheap but not much of it came home with me, just the 3 ton jack. Fun times!! For sure!!
